battery help

Ok so I've had this D2G from the day it came out , now I always use my phone from 100% to literally 0% and it used to gimme a good 10hrs nowadays I get 100%-30% in 30mins of me texting not even heavily at that o,O. I read on the forum something about "protected mode" and I'm wondering how does this affect my phone and is their anyway to get out if it ?

I am an eletrician and use battery drills and such. Over the years I have been told to drain batteries all the way and also not to. I think it was the changing battery technologies requiring different methods to prolong battery life.

Just for MY information, could you point me to a detailed thread/page explaining why it damages the battery.

Btw, I am NOT saying you are wrong. I really have no idea. Just curious...
